LEVER.

T o all w hom t may concern.'

Be it known that I, FREDERICK D. WVILsoN, a citizen of the UnitedStates, residing at Moline, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements in Levers,of which the following is a specification, reference being had thereinto the accompanying drawing.

My invention relates to levers commonly employed for adjustmentpurposes, and the object of my invention is to provide such a devicewith a novel and effective means of holding the lever at any point ofadjustment.

' Referring to the drawings in which similar numerals indicate identicalparts- Figure 1 is a side elevation of my improved device.

Fig. 2 is a front elevation in part section.

Fig. 3 is a front elevation in part section and showing the leverreleased for operation.

Fig. 4 is a detail in part section showing the lever in engagement witha tooth of the sector, and

Fig. 5 is a detail of part of the lever.Y

On a support 1 is rigidly secured a sector 2. A lever 3 is pivotallysupported on a bolt 4t which passes through the support 1 and the base 5of the sector 2; on the free end of the lever 3 is the usual grip 6.Slidably mounted on the lever 3 is a casting 7 having a part 8 whichextends above and to the side of the arc of the sector 2 opposite thelever 3. Preferably integral with the part 8, and extending downwardlytherefrom, is a projection 9 having its inner face beveled to contactwith a similar bevel 10 on the adj acent edge of the arc of the sector2. On the lever 3, above the casting 7, is rigidly secured a member' 11between the under side of which and the top of the casting 7 is a coiledspring 12 held secured in place by a stud 13 on the member 11 and asimilar stud 14 on the part 8 of the casting 7.

On the side of the arc of the sector 2 opposite the bevel 10 is a seriesof radially disposed teeth 15 any one of which is adapted to engage witha slot 16 in the lever 3. EX- tending from one side of the part 8 of thecasting 7 is an eye 17 in which the lower hook end of a rod 18 isengaged; the rod 18 extends upward and is connected to a SpecificationofLetters atent.

Vlrockable grip 19 pivotally mounted on the upper' portion of the lever3.

vAs shown in Figs. 1 and 2 the lever 3 is held in position by oneof theteeth 15 of the sector 2 engaging with the slot 16 in the lever, and thepressure of the projection 9 against the bevel 10 of the arc caused bythe expansive force of the coiledv spring 12. When it is desired toswing the lever 3 to a different position the two grips 6 and 19 arebrought together raising the casting 7, and as the latter raises lateralpressure Vis exerted by the operator to spring the lever 3 outward fromthe arc of the sector 2 to free the slot 16 from the tooth 15 with whichit has been engaged. j When the lever 3 is free to be rocked eitherforwardly or rearwardly the parts are in position, as shown in Fig. 3,the end of the projection 9 having the limit of its upward movementbelow the upper edge of the are, acts as a stop to prevent the lever 3from too great a lateral movement.

When the desired position of adjustment has been reached it is obviousthat when the operator releases his hold upon the lever 3 the latterwill spring back into place, the slot 16 engaging with the tooth 15opposite to which the lever 3 has been moved; simultaneously with thespring of the lever 3 back into position, thek casting 7 will movedownwardly under pressure of the spring 12 until the parts are as shownin Figs. 1 and 2, the bevel of the projection 9 resting firmly againstthe bevel 10 of the arc and holding the lever 3 securely in place.

What I claim is 1. In a lever mechanism, the combination of a sector, alever pivotally mounted to rock lengthwise of the sector, means on oneside of the arc coacting with means on the lever to hold the latter fromrocking, said means separable by springing the lever laterally wherebythe lever is free to be rocked, and means on the lever in contact withthe other side of the arc to hold the lever from lateral movement, saidmeans adapted to be raised to free the lever simultaneously with thelateral swing thereof.

2. In a lever mechanism, the combination of a sector, a lever pivotallymounted to rock lengthwise of the sector, teeth on the side of the arcadjacent the lever, said lever provided with a slot to engage with anyone of said teeth to hold the lever from rocking, and means on the leverin contact with the side of the are opposite the lever to hold i 'theylatter from lateral movement, said means adapted to be raised to freethe lever Sifrnultaneously with the lateral swing thereo 3. In a levermechanism, the combination of a sector, a leverpivotally mounted to rocklengthwise of the sector, teeth on the side of the arc adjacent thelever, said'lever provided with a slot to engage with any one of saidteeth to hold the lever from rocking, a bevel on. the opposite side ofthe are, and a casting slidably mounted on the lever and having `adownwardly extending projection lin Contact with the bevel of the arcrtohold the lever from lateral movement.

4. In a lever mechanism, the combination of aA sector, a lever pivotallymounted to rock lengthwise of the sector, teeth on` the side of the areadjacent the lever,said -lever provided with a slot to engage with anyone of the teeth toV hold the lever from rocking, a bevel on theopposite side of the are, a casting slidablymounted on the lever andhaving a downwardly'extending. projection a bevel on said projection inContact with the bevel on the are to hold the lever from lateralmovement.

5. In a lever mechanism, the combination of ka sector, a lever pivotallymounted toA abevel on said projection 'in contact with the bevel on thearc, a member rigidly secured -,on vthe lever, and -a vcoi-led springinterposed between said'member and the casting to hold the bevels incontact whereby the lever .is held from lateral movement.,
